The lack of a working MeCP2 protein — the most common cause of Rett syndrome — prematurely closes a window of neuronal plasticity in a brain region involved in social memory, a study showed. Neuronal plasticity is the brain’s ability to re-wire itself, to strengthen or weaken its neuronal connections, in response…

The loss of MECP2 protein — defective in most cases of Rett syndrome — in the lungs may result in breathing problems, according to a mouse study. The findings suggest that this may due to altered amounts of fats in the lungs, and could have important implications for treating…

Acadia Pharmaceuticals has completed enrollment in the Phase 3 clinical trial LAVENDER, which is testing the investigational medication trofinetide as a treatment for Rett syndrome. Top-line results from the study are expected later this year, according to a press release. LAVENDER (NCT04181723) enrolled approximately…

The Ontario Rett Syndrome Association (ORSA) announced the awarding of two grants to support research into Rett syndrome in Canada. According to an ORSA press release, grants totaling CA$78,750 (about $62,800) will be given to two selected projects. The funding comes from The Hope Fund, which ORSA…

A music-based intervention helped to normalize certain social behaviors in a mouse model of Rett syndrome, researchers reported. Findings also suggested that repeated, regular exposure to music altered the activity of certain genes in particular brain regions, yielding clues as to the biologic mechanisms through which the intervention works. The…

A first-generation university student has been awarded a six-year, $466,669 grant from the National Institutes of Health (NIH) to fund his doctoral and postdoctoral research into brain-derived neurotrophic factor (BDNF), a protein that plays a role in Rett syndrome. The Virginia Tech student, Raymundo Hernandez, called the NIH grant…

Shape Therapeutics has raised $112 million in financing to support work into developing its portfolio of RNA technologies to potentially treat genetic diseases, including Rett syndrome. “We have witnessed the power of [messenger RNA] in the vaccine space and are now entering a new era where we can…

The molecular mechanism by which the protein MeCP2 recognizes and binds to CA repeats — repetitive short sequences of DNA that are found throughout the genome — has been unraveled in a new study that sheds light on the causes of Rett syndrome. Researchers in France discovered that MeCP2…

Treatment with a protein called CNF1 produced different results in two different mouse models of Rett syndrome, demonstrating a need to test therapeutic approaches across disease models, according to a study. Specifically, the CNF1 protein was able to rescue cognitive deficits, but not motor difficulties, in a mouse model…

Using a virtual avatar to guide users during attention and memory tasks significantly improves the performance of people with Rett syndrome, according to a small study from Italy. The human-like interactive agent likely acts as a social motivator for these  patients, who often focus on the face of parents and…
